Better Water Resources Management: Part 3

Seawater Intrusion Modeling - How to Set Up, Run and Visualize with SEAWAT Numerical Model

   Watch Promo

Due to rapid urban development, climate change, intense agriculture and other factors shallow unconfined aquifers in a lot of coastal regions have become highly vulnerable to contamination from sea water intrusions.

The SEAWAT program is designed to simulate variable-density ground-water flow and solute transport in three dimensions. The underlying concept of SEAWAT is to combine an existing flow code (MODFLOW) with an existing solute-transport code (MT3DMS) to form a single program that solves the coupled flow and solute-transport equations.

One benefit of the SEAWAT approach is that improved and updated versions of the flow and transport codes can be incorporated into the SEAWAT program to take advantage of recent improvements. Another benefit is that users familiar with the constant-density versions of the flow and transport codes can easily apply the SEAWAT program to variable-density ground-water problems.

Course topics:

  • Set up 3D conceptual model in MODFLOW with 11 layers
  • Assign both MODFLOW and SEAWAT boundaries (for seawater intrusion model)
  • Properly set up different parameters in SEAWAT
  • Run the transient SEAWAT seawater intrusion model
  • Visualize results in 3D
  • Learn which groundwater sampling method works the best in coastal zones influenced by seawater intrusion?
  • Learn what are typical groundwater discharge rates in coastal zones around The World - compare it with your model to validate it.
  • Analyzing local and regional SEAWAT model for water resources management - case study from USGS (United States Geological Survey)

Who should attend?

This course is ideally suited for hydrogeologists, environmental engineers and climate change experts as an additional skill to make informed decisions in coastal zones.


B.Sc in hydrogeology, geology, environmental engineering, civil engineering.

Dragan Kaludjerovic, PhD
Dragan Kaludjerovic, PhD

Dragan Kaludjerovic received his BSc, MSc an PhD at Belgrade University and he is currently at online specialization at The Johns Hopkins University - Environmental Engineering.

In his early career, 1998, Dr. Kaludjerovic focused his research on more complicated numerical models such as unsaturated zone modeling and transport modeling with MT3DMS. Feedback from his presentation at the MODFLOW 98 Conference influenced him to continue to work on mathematical models and their application to hydrogeology engineering which resulted in his MSc defense.

Later, in 2000, he was invited to work at Waterloo Hydrogeologic Inc, (WHI), a world leader at that time in groundwater model software development and consulting. During his time at WHI, he was introduced to innovative modeling techniques, including PEST for parameter estimation and reactive transport modeling with RT3D.

During the next several years, Dr. Kaludjerovic worked on numerous projects including the design of a large groundwater source with 1000 l/s in Macedonia.

In 2005, Dr. Kaludjerovic started work on his PhD thesis which was completed in 2008 and titled "Natural Attenuation of Contamination in Groundwater". The scope of this thesis focused on applications of the RT3D (Reactive Transport) model with multiple electron acceptors to a field case (aquifer contaminated with xylene).

After his PhD thesis, Dr Kaludjerovic continue to conduct research in the area of aerobic and anaerobic bioremediation with emphasis on emulsified oil projects and gas infusion technologies. During his carrier Dr Kaludjerovic published more then 25 papers which can be found below or on his Linkedin page.

In last several years, Dr Kaludjerovic is working with high resolution satellite images (both optical and radar satellites) and its application in environmental science and modeling.

What our Clients Say About Us

Dragan is a fantastic technical resource. With his assistance, I’ve been able to greatly improve my groundwater modeling and GIS skills. I will continue to seek him out for my professional development needs. He provided great value and was a pleasure to work with!
- Bob Marley - Senior Hydrogeologist at EA Engineering, Science, and Technology, Inc., PBC

I have known Dragan for many years. I am most impressed with his dedication to hard work, and the breadth of his knowledge on environmental data acquisition and processing, software, and modelling.
- John Doherty Owner, Watermark Numerical Computing, Australia

He is always available for questions and truly goes above and beyond in his training classes. I have gained a lot of knowledge over a short period of time working with Dragan and would highly recommend his services to others.”

- Thomas Ballard, PG, CHG, Consulting Hydrogeologist, USA

I took multiple training courses with Dragan. I learned a great deal with him during each of the courses. He is an excellent teacher willing to help out in any way possible.
- Mark Sherrill, Environmental Scientist at Short Elliott Hendricson, USA

"I recently completed a course in Remote Sensing and QGIS with Dragan. He was very knowledgeable and guided me through the theory and background and also the implementation of remote sensing. He was very personable and happy to answer all my questions. I appreciate having him as a reference and would recommend him to anyone interested in this topic."
- Lea Bergwall, GIS Analyst, USA
